-    * Qt 5: `qt5-qtsvg-devel qt5-qtquickcontrols2-devel`
-* Building the Vulkan renderer requires a `libplacebo-dev`/`libplacebo-devel` version of at least v7.349.0 and FFmpeg 6.1 or later.
 
 ### Steam Link Build Requirements
 * [Steam Link SDK](https://github.com/ValveSoftware/steamlink-sdk) cloned on your build system
 * STEAMLINK_SDK_PATH environment variable set to the Steam Link SDK path
 
-**Steam Link Hardware Limitations**  
-Moonlight builds for Steam Link are subject to hardware limitations of the Steam Link device:
-* Maximum resolution: **1080p (1920x1080)**
-* Maximum framerate: **60 FPS**
-* Maximum video bitrate: **40 Mbps**
-* **HDR streaming is not supported** on the original hardware
-
-### Docker containers
-If you want to use Docker for building, look at [this repo](https://github.com/cgutman/moonlight-packaging) containing canonical containers
-for different architectures, which handle building deps and extra linking for you.
-
 ### Build Setup Steps
 1. Install the latest Qt SDK (and optionally, the Qt Creator IDE) from https://www.qt.io/download
     * You can install Qt via Homebrew on macOS, but you will need to use `brew install qt --with-debug` to be able to create debug builds of Moonlight.
-    * You may also use your Linux distro's package manager for the Qt SDK as long as the packages are Qt 5.12 or later.
+    * You may also use your Linux distro's package manager for the Qt SDK as long as the packages are Qt 5.9 or later.
     * This step is not required for building on Steam Link, because the Steam Link SDK includes Qt 5.14.
-2. Download submodules and dependencies
+2. Run `git submodule update --init --recursive` from within `moonlight-qt/`
-    * Run `git submodule update --init --recursive` from within `moonlight-qt/`.
-    * On Windows and macOS, you must also run `setup-deps.ps1` (Windows) or `setup-deps.py` (macOS).
-    * Perform these steps each time you pull new changes from the Git repository.
 3. Open the project in Qt Creator or build from qmake on the command line.
     * To build a binary for use on non-development machines, use the scripts in the `scripts` folder.
         * For Windows builds, use `scripts\build-arch.bat` and `scripts\generate-bundle.bat`. Execute these scripts from the root of the repository within a Qt command prompt. Ensure  7-Zip binary directory is on your `%PATH%`.
         * For macOS builds, use `scripts/generate-dmg.sh`. Execute this script from the root of the repository and ensure Qt's `bin` folder is in your `$PATH`.
         * For Steam Link builds, run `scripts/build-steamlink-app.sh` from the root of the repository.
-    * To build from the command line for development use on macOS or Linux, run `qmake6 moonlight-qt.pro` then `make debug` or `make release`.
+    * To build from the command line for development use on macOS or Linux, run `qmake moonlight-qt.pro` then `make debug` or `make release`
-        * The final binary will be placed in `app/moonlight`.
+    * To create an embedded build for a single-purpose device, use `qmake "CONFIG+=embedded" moonlight-qt.pro` and build normally.
-    * To create an embedded build for a single-purpose device, use `qmake6 "CONFIG+=embedded" moonlight-qt.pro` and build normally.
         * This build will lack windowed mode, Discord/Help links, and other features that don't make sense on an embedded device.
-        * For platforms with poor GPU performance, add `"CONFIG+=gpuslow"` to prefer direct KMSDRM rendering over GL/Vulkan renderers. Direct KMSDRM rendering can use dedicated YUV/RGB conversion and scaling hardware rather than slower GPU shaders for these operations.
+        * For platforms with poor GL performance, add `"CONFIG+=glslow"` to prefer direct KMSDRM rendering over EGL/GLES renderers. Direct KMSDRM rendering can use dedicated YUV/RGB conversion and scaling hardware rather than slower GPU shaders for these operations.
